Dave, If your power supply is 13.8 volts, you can expect more power output than that. Check into a known good 50 ohm dummy load with the tuner removed and the jumper in place.
If you still have problems, check T1 and the Low Pass Filter (L1 and L2 and associated capacitors) for proper winding, good lead stripping, and proper values. A typical KX1 will provide almost 4 watts out on 40 meters and about 3.5 watts on 20, but anywhere in the range of 3 to 4 watts is the specification, so if you can get both bands above 3 watts, it passes. The receiver sensitivity is not related to the transmit problem unless you have a gross error in the Low Pass Filter - differnt circuits are used for transmit than those for receive (the trimmers are only for the receiver front end tuning, not transmit). 73, Don W3FPR > -----Original Message----- > > I just finished my KX-1.
